[LayoutNG] Allow spanners inside a transform

Previously, CanContainSpannerInParentFragmentationContext() would not
allow spanners that are the descendant of a transform. However, the
containing block chain now goes directly from the column spanner
to the multicol container for an NG multicol. Thus, it is safe to
allow a spanner to be a true column spanner if it is a descendant of
a transform (in the case that the multicol is an NG object).
